Charlie Chaplin's 57th Film released November 13 1916.
Behind the Screen, a short film written and directed by Charlie Chaplin also starring Eric Campbell and Edna Purviance. In the film which takes place in a movie studio, Chaplin plays a stagehand named David while Campbell ("Goliath") plays his supervisor. Much of the film is slapstick comedy but other issues are also brought up such as a stagehand strike as well as a plotline in which Purviance, unable to become an actress, dresses as a man and becomes a stagehand. The film is silent.
The film is noted for having one of the first Hollywood gay jokes in it. After Chaplin learns that Purviance is really a woman, he kisses her while on the set. A male stagehand sees this and thinking that Chaplin has kissed a man, starts acting in an overtly effeminate way until Chaplin kicks him.
